A Basic Input/Output System (BIOS) is an electronic set of instructions that a Personal Computer (PC) uses to successfully start up.

It is located on a chip on the motherboard inside of a computer and is designed to be protected from disk failure.

While it can be updated, this should be done carefully to avoid damaging the computer or leaving it unable to start up.

Certain computer manufacturers, such as Apple™, use other systems like Open Firmware.

One of the main functions of the BIOS is to give instructions for the Power-On Self Test (POST).

This self test ensures that the computer has all of the necessary parts and functionality needed to successfully start itself, such as use of memory and a keyboard and other components.
